IMPROVEMENT IN FASTENINGS FOR THE MEETING-RAILS OF SASHES.

Specification forming part of Letters Patent No. 130,970, datedSeptember 3, 1872.

T 0 all persons to whom these presents may come: Be it known that I, JOHN ANDREWS, of Marlborough, of the county of Middlesex and State ofMassachusetts, have invented a new and useful ImprovementinWindow-SashFasteners; and do hereby declare the same to be fullydescribed in the following specification and represented in theaccompanying drawing, of which- 7 Figure 1 is a top View, and Fig. 2 afron elevation, of one of my improved sash-fasteners. Fig. 3 is a frontview of the notched catch. Fig. 4 is a top view of the segmentalcatchlever plate. Fig. 5 is a rearedge view; Fig. 6 is a side-edge view;and Fig. 7 is an underside view of such catch-lever plate.

The fastener, constructed as represented, is designed to be used uponwindows whose sashes have a middle vertical bar to the upper or each ofthem.

With sashes so made it has been customary either to use with the twosashes two fastenings, arranged on opposite sides of the middle uprightbar of the upper sash, or, in the plac'e of two fasteners so disposed, asingle fastener placed aside of such bar, the latter being anobstruction or impediment to the arranging of the fastener at themiddles of the contiguous or next adjacent horizontal bars of the twosashes.

Owing to the construction of present improved fastener, it, like anotherfor which I recently obtained a patent No. 122,348, dated January 2,1872, can be applied to the middles of the said sash-bars lastmentioned, as it will straddle the middle vertical bar of the uppersash.

In my present sash-fastener the catchlever is not pivoted to the partwhich straddles the upright middle bar of the sash, but is a hookedlever pivoted to the plate, which is secured to the front sash, and thepart which straddles the sash is formed with a notch, opening, or vrecess, to receive the hook of the catch-lever while such lever is beingturned on its pivot so as to en gage with the catch part.

From the above it will be seen that the catch part is not only made witha notch to receive the upright sash-bar, but also has a 1catch-notch toreceive the book of the catchever.

The segmental stop-plate to which'the catchlever is pivoted is providedwith two stopand hold the lever-catch in either of its two extremepositions, it being capable of being turned through an arc of ninetydegrees. In the drawing, A denotes the segmental stop-plate, providedwith a pivot, a, to receive the catch-lever B, formed as shown, with ahooked end, I), and furnished with a handle or knob, c. This plate A isto be fastened to the top bar of the lower sash by screws going downthrough holes made in the plate. The two shoulders of the plate arerepresented at d e, and the. inclined planes or cams leading down fromthem and meeting together are shown at g h. The notched catch-plate, tobe fixed to the lower horizontal bar of the upper sash, is representedat G, as having the sashbar or straddle-notch i, and as formed with arecess or notch, 70, for reception of the hook of the lever, all beingas shown in the drawing. When the catch-lever is against the shoulder clof the segmental plate the fastener will be locked; but when such leveris against the other shoulder, e, such fastener will be unlocked, or theback of the catch-lever will be out of the holding-notch k of the plate0, and entirely over the segmental plate A, the lever having been madeto ride upon the inclined plane or cam next to the stop or shoulderagainst which it may then be. This plane or cam will hold the lever frombeing accidentally turned out of position. In drawing the lever aroundso as to lock the fastener, such lever will raise the other inclinedplane and slip into the notch between such and the front shoulder, andwill be held by such connection with" the catch part 0 until again movedby the hand applied to the knob of the lever.

One important difference between my present sash-fastener and thatdescribed in the aforesaid patent is, that the catch-lever is pivoted tothe part which is screwed to the front sash, and is pivoted to themiddle thereof instead of being arranged aside of the middle of itssupporter, as is the case in my said patented fastener. There are otherdifferences which are visible, and go to render the present fastenerfarbetter, both in construction it, as shown, the latter notch being forrecepand operation. tion of a hooked lever, B, made and pivoted I hereinmake no claim to the subject of my to a plate, A, as set forth.
